Subject: [dpdk-dev] [PATCH v2 0/2] ring: allow to init a rte_ring outside of an rte_memzone

These 2 patches adds 2 new functions that permits to initialize and use
a rte_ring anywhere in memory.

Before this patches, only rte_ring_create() was available. This function
allocates a rte_memzone (that cannot be freed) and initializes a ring
inside.

This series allows to do the following:
  size = rte_ring_get_memsize(1024);
  r = malloc(size);
  rte_ring_init(r, "my_ring", 1024, 0);


Changes included in v2:
  - fix syntax for functions definitions in rte_ring_get_memsize()
  - use RTE_ALIGN() to get nearest higher multiple of cache line size
  - fix description of rte_ring_init() in doxygen comments

Olivier Matz (2):
  ring: introduce rte_ring_get_memsize()
  ring: introduce rte_ring_init()
